2012-09-23viafb: don't touch clock state on OLPC XO-1.5Daniel Drake1-0/+19
As detailed in the thread titled "viafb PLL/clock tweaking causes XO-1.5 instability," enabling or disabling the IGA1/IGA2 clocks causes occasional stability problems during suspend/resume cycles on this platform. This is rather odd, as the documentation suggests that clocks have two states (on/off) and the default (stable) configuration is configured to enable the clock only when it is needed. However, explicitly enabling *or* disabling the clock triggers this system instability, suggesting that there is a 3rd state at play here. Leaving the clock enable/disable registers alone solves this problem. This fixes spurious reboots during suspend/resume behaviour introduced by commit b692a63a.

equalization To check channel equalization, the value of LANE_ALIGN_STATUS_UPDATED is necessary in exynos_dp_channel_eq_ok(). Also, link_align includes this value. However, link_status does not include this value, so it makes the problem that channel equalization is failed during link training.

It is expected that LCDC to continue to be disabled after resume if it is blanked before suspend. This is also true for DVFS.

2012-08-23OMAPDSS: Fix SDI PLL lockingTomi Valkeinen1-0/+14
Commit f476ae9dab3234532d41d36beb4ba7be838fa786 (OMAPDSS: APPLY: Remove DISPC writes to manager's lcd parameters in interface) broke the SDI output, as it causes the SDI PLL locking to fail. LCLK and PCLK divisors are located in shadow registers, and we normally write them to DISPC registers when enabling the output. However, SDI uses pck-free as source clock for its PLL, and pck-free is affected by the divisors. And as we need the PLL before enabling the output, we need to write the divisors early. It seems just writing to the DISPC register is enough, and we don't need to care about the shadow register mechanism for pck-free. The exact reason for this is unknown.

Pull SCSI target fixes from Nicholas Bellinger: "The executive summary includes: - Post-merge review comments for tcm_vhost (MST + nab) - Avoid debugging overhead when not debugging for tcm-fc(FCoE) (MDR) - Fix NULL pointer dereference bug on alloc_page failulre (Yi Zou) - Fix REPORT_LUNs regression bug with pSCSI export (AlexE + nab) - Fix regression bug with handling of zero-length data CDBs (nab) - Fix vhost_scsi_target structure alignment (MST) Thanks again to everyone who contributed a bugfix patch, gave review feedback on tcm_vhost code, and/or reported a bug during their own testing over the last weeks. There is one other outstanding bug reported by Roland recently related to SCSI transfer length overflow handling, for which the current proposed bugfix has been left in queue pending further testing with other non iscsi-target based fabric drivers. As the patch is verified with loopback (local SGL memory from SCSI LLD) + tcm_qla2xxx (TCM allocated SGL memory mapped to PCI HW) fabric ports, it will be included into the next 3.6-rc-fixes PULL request." * git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending: target: Remove unused se_cmd.cmd_spdtl tcm_fc: rcu_deref outside rcu lock/unlock section tcm_vhost: Fix vhost_scsi_target structure alignment target: Fix regression bug with handling of zero-length data CDBs target/pscsi: Fix bug with REPORT_LUNs handling for SCSI passthrough tcm_vhost: Change vhost_scsi_target->vhost_wwpn to char * target: fix NULL pointer dereference bug alloc_page() fails to get memory tcm_fc: Avoid debug overhead when not debugging tcm_vhost: Post-merge review changes requested by MST tcm_vhost: Fix incorrect IS_ERR() usage in vhost_scsi_map_iov_to_sgl

2012-08-22vfio: grab vfio_device reference *before* exposing the sucker via fd_install()Al Viro1-2/+2
It's not critical (anymore) since another thread closing the file will block on ->device_lock before it gets to dropping the final reference, but it's definitely cleaner that way... Acked-by: Alex Williamson <alex.williamson@redhat.com> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2012-08-22vfio: get rid of vfio_device_put()/vfio_group_get_device* racesAl Viro1-2/+1
we really need to make sure that dropping the last reference happens under the group->device_lock; otherwise a loop (under device_lock) might find vfio_device instance that is being freed right now, has already dropped the last reference and waits on device_lock to exclude the sucker from the list.
